When did Sheriam swear to Egwene?

[Emerikol the Chaotic]

I'm re-reading the series, and I seem to have read past this bit or something. I've looked through the EncyclopediaWOT, and I can't find a reference.

 

Would someone be so kind as to give me a book & chapter reference for when Sheriam and Carlinya swear fealty to Egwene?

 

Thanks very much.

It happens later in the day after Morning of Victory in CoS has ended, though we don't see it. Faolain and Theodrin had sworn earlier, then Nisao and Myrelle swore, and were sent to fetch the rest of Sheriam's click to Egwene for the swearing. In PoD it is already referenced as having happened.
